Suppose a disk drive has the following characteristics: Six surfaces 16,383 tracks per surface 63 sectors per track 512 bytes/sector Track-to-track seek time of 8.5ms Rotational speed of 7,200rpm a) What is the capacity of the drive
Answer:
The answer is "2.95 GB"
Explanation:
Given value:
Surfaces = 6
The tracks per surface =16,383
The sectors per track = 63
bytes/sector = 512
Track-to-track seek time = 8.5ms
The Rotational speed = 7,200rpm
[tex]\text{Drive capacity= surface} \times \text{tracks per surface} \times \text{sectors per track} \times \frac{bytes}{sector}[/tex]
[tex]= 6 \times 16383 \times 63 \times 512 \\\\= 3170700288 \ B\\\\ = 3023.81543 \ MB \\\\= 2.95294 \ GB\\[/tex]

Write a method called printIndexed that accepts a String as itsparameter and prints the String's characters in order followed bytheir indexes in reverse order. For example, the call ofprintIndexed("ZELDA"); should print Z4E3L2D1A0 to the console.
Answer:
def printIndexed(s):
for i in range(len(s)):
print(s[i] + str(len(s) - 1 - i), end="")
printIndexed("ZELDA")
Explanation:
*The code is in Python.
Create a method named printIndexed that takes one parameter, s
Create a for loop that iterates the length of the s times
Inside the loop, print the characters from starting and indexes from the end
Note that in order the print the current character, you need to use indexing. s[i] refers to the current character of the string (the value of the i starts from 0 and goes until length of the s - 1). Also, to print the indexes from the end, you need to subtract the i from the length of the s - 1
For example, in the first iteration, i = 0:
s[i] = s[0] = Z
len(s) - 1 - i = 5 - 1 - 0 = 4
11000011 00010011 00111010 00011101 / 00010010
In this example of IP address, determine: class, hostID, netID.

Write a class named TestScores. The class constructor should accept an array of test scores as its argument. The class should have a method that returns the average of the test scores. If any test score in the array is negative or greater than 100, the class should throw an IllegalArgumentException. Demonstrate the class in a program.
import java.util.Arrays;
public class TestScores {
public static float getAverage(float arr[]){
float total = 0;
for (float x : arr){
if (x < 0 || x > 100){
throw new IllegalArgumentException();
}
else{
total += x;
}
}
return (total / arr.length);
}
public static void main(String [] args){
float arr[] = {1,100,0,43,-1};
System.out.println(getAverage(arr));
}
}
In the main method we test our getAverage method with the arr array. You can replace the values in the arr array and test your own values. I hope this helps!
The code example of the implementation of the TestScores class in Java is shown below:
What is the class?java
import java.util.Arrays;
public class TestScores {
private int[] scores;
public TestScores(int[] scores) {
this.scores = scores;
}
public double getAverage() {
int sum = 0;
for (int score : scores) {
if (score < 0 || score > 100) {
throw new IllegalArgumentException("Invalid test score: " + score);
}
sum += score;
}
return (double) sum / scores.length;
}
public static void main(String[] args) {
int[] scores = {85, 90, 92, 88, 95};
TestScores testScores = new TestScores(scores);
try {
double average = testScores.getAverage();
System.out.println("Average test score: " + average);
} catch (IllegalArgumentException e) {
System.out.println("Error: " + e.getMessage());
}
}

Give a recursive algorithm that takes as input two non-negative integers x and y and returns the sum of x and y. The only arithmetic operations your algorithm can perform are Increment(x) which returns x 1 and Decrement(x) which returns x-1. Your algorithm should have no loops.
Answer:
Following are the code to this question:
Cal_sum(x,y)//defining a recursive method Cal_sum that takes two variable as a parameter
{
if(x==0)// defining If that checks x equal to 0
return y; //return y value
x- 1;//decreasing x value
y+1;//increasing y value
return Cal_sum(x,y)// calling method recursively
}
Explanation:
In the above-given code, a recursive method "Cal_sum" is declared, that accepts two-variable "x and y" in its parameter, and use if block to checks x is equal to 0 and return the value y variable, and, in the next step, it decreases the value of " x" by "1" and increment the value of y by "1", and call the method "Cal_sum" recursively.
The recursive program which calls itself in a function is used to return the value of y for a given x, y value in the program. The code written in python 3 goes thus :
def calc_sum (x,y) :
#initializes a function named calc_sum which takes in two arguments
if x ==0 :
#checks of the value of x is equal to 0
return y
#it returns y if x == 0
else :
#otherwise
x = x - 1
# decrease the value of x by 1
y = y + 1
#increase the value of y by 1
return calc_sum(x,y)
# calls the function recursively until x ==0
A sample run of the program is given below
print(calc_sum(4, 5 ))

Write a program to simulate a simple calculator. In your program ask the user to enter an operation selected from the menu, ask for two operands. Calculate the result and display it on the screen. Here is a sample run
Answer:
Written in Python:
opcode = input("Enter operator: +,-,*,/")
operand1 = float(input("Operand 1: "))
operand2 = float(input("Operand 2: "))
if opcode == "+":
print(operand1 + operand2)
elif opcode == "-":
print(operand1 - operand2)
elif opcode == "*":
print(operand1 * operand2)
elif opcode == "/":
print(operand1 / operand2)
else:
print("Invalid Operator")
Explanation:
This prompts user for operator
opcode = input("Enter operator: +,-,*,/")
The next two lines prompt user for two operands
operand1 = float(input("Operand 1: "))
operand2 = float(input("Operand 2: "))
This performs + operation if operator is +
if opcode == "+":
print(operand1 + operand2)
This performs - operation if operator is -
elif opcode == "-":
print(operand1 - operand2)
This performs * operation if operator is *
elif opcode == "*":
print(operand1 * operand2)
This performs / operation if operator is /
elif opcode == "/":
print(operand1 / operand2)
This displays invailid operator if input operator is not +,-,* or /
else:

Infrastructure as a Service (IaaS) replaces the _________ of the computer hierarchy with an Internet-based infrastructure.A. digital logic level through user levelsB. digital logic level through high-level language levelsC. system software level through high-level language levelsD. digital logic level through machine levels
Answer:
D. digital logic level through machine levels
Explanation:
In Computer science, the modern computer systems are basically organized in levels and this is known as computer hierarchy. The three levels in a chronological order are operating system level, machine language level and digital (hardware) logic level.
A digital logic level is the most fundamental level of a computer and can be defined as a level of the computer hierarchy which typically comprises of wires and gates. In digital circuits, the two (2) main logic level of the binary logic state are logical low and logical high which is typically denoted by the number 0 and 1 respectively.
In Computer science, the Infrastructure as a Service (IaaS) replaces the digital logic level through machine levels of the computer hierarchy with an Internet-based infrastructure. This is what enables various users to access resources that are available over the internet through the use of cloud storage.
